Hmmm, interesting page. I am watching:
http://newdos.yginfo.net/msdos71/whatsnew.htm
I see a couple of inaccuracies, such as Euro Sign support can't be in
850, but 858 (andAltGr+5 in some keyboards, AltGr+E in mine).
However, it talks about LFN support, but AFAIK this is implemented in
VFAT, not in MS-DOS kernel. At least my Win98 DOS (MS-DOS 7.10) can't
see LFNs, so unless the author has taken the shots on a Win9X DOS box,
do you know how is that he mentions and has screenshots of DOS with LFNs?
